This is a patch release fixing two minor issues.

The detailed list of changes introduced in this release follows.
New Features
  • None.
Fixed Problems
  • Do not set the header field Ocp-Apim-Subscription-Key in the outgoing request when the subscription key is not specified (on-prem containers). This is a regression introduced since Azure SR 1.19.0 with the support of private endpoints causing no functional differences in most of the cases.
  • Consistently set the header field Input-Type to 'speech' and/or 'dtmf' in the START-OF-INPUT events.
Configuration Parameters
  • None.
  • None.

Thank you for using UniMRCP.
